I noticed this today. But I was told by a friend of mine there IS a reason why she's not there and I don't want to spoil it.
I also noticed one thing that people seem not to notice: since (SPOILER)Shinra is destroyed in the end of FF VII, in Japanese magazines the're not referred as the Turks, but the EX- Turks. So why are they still wearing ecactly the same uniform they had before?
